The general working principle of GEPARD is explained herein.
Setup the gepard.cfg
For optimal use, please create a copy of the sample_gepard.cfg and rename it to gepard.cfg. Within this config-file, a default file path and the Raman Control Interface that shall be used is defined. Further (microscope specific) options can be defined as well.
Using GEPARD with WITec Raman mircoscopes
As long as you don't do anything with your WITec software GEPARD won't be able to interfere with the microscope. Gepard itself is not able to directly connect to the Raman microscope and uses for example WITec-Control for this purpose. This remote access needs to be actively enabled in the WITec Control software.
Make sure that you have at least Version 5.0 of WITec-Control installed. In versions prior to 5.1 activate Default Tree mode (right click in the left control panel). Then activate "Allow Remote Access". This remote access can be revoked at any time with a large button in WITec Control. After the access is denied again your WITec Control should run as before. Now, try the witectest.py sample first with objectives turned away from the samples.
To activate the WITec backend for GEPARD set the 'raman_interface' variable to 'WITEC_CONTROL' in gepard.cfg. Restart GEPARD to activate the new configuration.
Creating and performing a measurement
After starting the GEPARD, a new measurement can be created by hitting the "New Measurement"-Button. A prompt window asks for a project name. GEPARD will create a directory with this name and save all required data within this folder. A project file will be saved as well, currently implemented by using the pickle module.
After creation of the experiment, GEPARD leads the user throught the following steps, as also indicated in the toolbar-menu on the left-hand side of the program:
